A nurse is assisting with the care of a school-age child who has shigella. Which of the following actions should the nurse take?

A. Antidiarrheal agents are generally avoided in cases of shigella infection, as they can slow the elimination of the bacteria and worsen the infection. B. A diet high in sodium is not appropriate; instead, oral rehydration therapy (ORT) is recommended to replace fluids and electrolytes lost during diarrhea. C. Shigella is a bacterial infection, not a viral one, so antiviral medications would not be effective. Antibiotics may be prescribed in some cases, but antivirals are not appropriate. D. Oral rehydration therapy is crucial to prevent dehydration and restore lost fluids and electrolytes in children with diarrhea from shigella.
